I have owned this many years and purchased it in an antique shop in Hong Kong in 1990. I have seen copies of this design but they are smaller and much lighter with far less definition in the chasing and design throughout. This is the real deal, and I consider it to be dating from the 1920's. My price is the lowest that I've seen for the antique original, so please do look around.  

Please see the images attached, of this superbly made antique statement piece of jewellery / evening wear.
